Christine, Jo and Mehdi communicate in (mostly) Spanish
Unable to speak French or English, Christine, Jo and Mehdi decide to communicate in Spanish, with Mehdi in the bin directing.
One of the instructions he repeats often is "todo recto" ('straight ahead'), thus coining the episode title.
The team's communication does occasionally stray into made-up words, and some French and English words, but they are not penalised for this.
They successfully complete all of the obstacles, but Mehdi is the one who bursts the balloon, which leads to an in-studio discussion over who the 'conductors' are, in the task.
The team is ultimately penalised for this infraction, receiving 4 points despite completing the course fastest, in 3 minutes and 28 seconds.
